Example of counting distinct bands and visible squares.
Then there are two squares in band 4, three squares in band 5, …, and three squares in
band 11. There are four distinct dark bands, and six distinct bright bands. This is because
the top three dark bands are indistinguishable.
Use the values in the following table to quantitatively compare images. For example, to
determine if a PACS supports GE VOI-LUTs, compare PACS Test Images 1 and 6. If the
number of distinct bands and visible squares are equal, then the PACS correctly supports
VOI-LUTs.
Record the results of tests as shown below. Record a description of the test below your
